PROSAUNAS Alder 3×3 S4SEE SHP is a premium engineered sauna wood designed to provide structural strength and a refined finish for benches and support frameworks. With smooth faces on all four sides and gently eased edges, it delivers both durability and comfort in high-use areas.
Alder is a trusted sauna material known for its consistent grain, smooth texture, and reliable performance in high-heat environments. It resists splintering and remains comfortable to the touch, making it ideal for structural and seating applications.
Each piece features an SHP (Square Edge Profile), offering clean, defined lines and versatile use for framing, supports, and bench construction. Its precise dimensions and engineered stability ensure easy installation and long-term performance.
PROSAUNAS selects high-quality alder to ensure uniform color, fine texture, and dependable durability. Suitable for both residential and commercial sauna builds, it’s a reliable choice for strong, long-lasting construction.

Read their reviews where they can't curate them, Trustpilot, not their own widget; read the one-star reviews and watch how they respond when freight goes sideways. You can see our Trustpilot reviews here
Ask what happens when a unit arrives damaged, you're listening for a person who owns it, not store-blames-manufacturer ping-pong.
Get the delivered price in writing before payment, "freight quoted after purchase" is the oldest move in the category.
Ask for a name, if nobody owns your order, nobody owns your problem.
